I was surprised to hear the Native Pronunciation of -rr- in the place name Wirral as voiced alveolar stop/tap -d- in this video as spoken by a native centenarian at the time point 0:47:
Is this the standard pronunciation for the -rr- in NW England, or is it standard English? This seems to be the reverse of the American rhoticity of the intervocalic -t- in words like "scooter". I would like to gain greater clarity into the phonetics involved here. Thank you!
